This research paper by Energy Innovation evaluates the potential impacts of two divergent U.S. policy pathways on greenhouse gas emissions, the economy, and public health through 2050. It compares a 'Continued Climate Leadership' scenario, aimed at meeting the U.S. Nationally Determined Contribution (NDC), against a 'Project 2025' scenario, which involves repealing major climate laws and expanding fossil fuel production. The analysis finds that the Continued Climate Leadership pathway would significantly reduce emissions, create millions of jobs, and lower household energy costs, while the Project 2025 pathway would increase emissions, lead to substantial job losses, and raise energy costs for households.

This research paper examines how energy network regulation in the UK can be adapted to manage uncertainties associated with net zero climate policy, utilizing theories of adaptive regulation and lessons from other sectors.

This briefing by the Stockholm Environment Institute outlines strategies for a just transition to a fossil-free transport system in Sweden. It identifies the socio-economic and geographic groups most at risk of negative impacts—particularly those in low-population density areas—and proposes a policy framework to ensure equity and political acceptance.

The 'Assessing Subnational Enabling Framework Conditions for Urban Climate Finance' guide, developed by the Cities Climate Finance Leadership Alliance (CCFLA) and the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP), provides a tool for subnational governments to evaluate and improve the regulatory, institutional, and financial environments necessary to scale urban climate finance.

Energy Innovation has released version 4.0 of the United States Energy Policy Simulator (EPS), an open-source model updated to incorporate the impacts of the Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA). The updated model features a rebuilt electricity sector with hourly dispatch and expanded power plant types to better analyze the financial incentives and emissions trajectories of the U.S. energy system through 2050.

The International Institute for Sustainable Development (IISD) statement celebrates the passage of the Canadian Sustainable Jobs Act (Bill C-50), which establishes a framework to support workers, Indigenous Peoples, and communities during Canada's transition to a low-carbon economy.

This report by the International Institute for Sustainable Development analyzes the scale of Canadian public financing for the fossil fuel sector and provides recommendations for a comprehensive policy to eliminate such financing to support the energy transition.

This document is the 2024 IRS Form 990 'Return of Organization Exempt From Income Tax' for the Stockholm Environment Institute (SEI) U.S., Inc., a 501(c)(3) non-profit organization based in Somerville, Massachusetts. The filing details the organization's financial activities, governance, and program accomplishments for the 2024 calendar year, focusing on its mission to provide research and decision-support tools for sustainable development, energy, water, and climate policy.

The International Institute for Sustainable Development proposes amendments to Bill C-50, the Canadian Sustainable Jobs Act, to enhance its accountability, inclusivity, and integration with climate policies, noting that while the bill provides a useful governance framework, existing gaps limit its efficacy.

The 2023 update report by the NewClimate Institute analyzes projected greenhouse gas (GHG) emissions up to 2030 for 25 countries, comparing current policy outcomes against Nationally Determined Contributions (NDCs). While aggregated emissions projections remain stable, the report identifies significant shifts in individual countries and a persistent gap between current policies and the 43% reduction required for Paris Agreement alignment.

This research paper by the NewClimate Institute examines the relationship between Nationally Determined Contribution (NDC) ambition and the adoption of national climate policies, arguing that increasing targets without corresponding policy implementation creates a credibility gap and undermines the Paris Agreement.

This briefing from the World Resources Institute argues that carbon mineralization requires increased and customized federal policy support to reach its potential for large-scale carbon removal. While some funding exists through broad carbon removal initiatives, the document highlights a gap in dedicated support compared to technologies like direct air capture and outlines necessary advancements in research, deployment incentives, and safety regulations to scale the technology responsibly.

This briefing by RMI examines the debate over emissions accounting methods in New York State, specifically focusing on the shift to a 20-year global warming potential (GWP20) timeframe and the inclusion of upstream and biogenic emissions. The author argues that this 'new climate math' increases climate benefits without necessarily increasing costs, as physical emissions remain constant regardless of the accounting timeframe used.

This research paper by the NewClimate Institute analyzes the relationship between the number of climate policies in force and projected greenhouse gas emission change rates between 2021 and 2030, identifying specific policy gaps in countries with high or stalling emissions.

This report examines how countries can use the outputs and results of the National Adaptation Plan (NAP) process to develop Adaptation Communications (AdComs) for the United Nations Framework Convention on Climate Change (UNFCCC), aiming to increase the visibility of adaptation efforts without increasing reporting burdens.

The Stockholm Environment Institute (SEI) provides expert comments to the Washington Department of Ecology regarding the potential linkage of Washington's cap-and-invest program with the Western Climate Initiative (WCI) market administered by California and Quebec. SEI warns that because Washington's program is currently more stringent and has a longer time horizon (through 2050) than California's (authorized through 2030), full linkage could significantly lower allowance prices, reduce state auction revenues, and undermine Washington's emission reduction goals. SEI recommends that full linkage be contingent on California extending its program beyond 2030 and increasing its 2030 cap stringency to address a large bank of unused allowances. As an interim measure, SEI proposes 'restricted linkage' via a quota on imported WCI allowances to balance cost containment with environmental integrity.

This briefing by the Stockholm Environment Institute analyzes the distributional welfare impacts of the 2022 energy price crisis in Sweden. It examines how electricity and fuel price increases affected different income deciles and geographical regions, evaluating the effectiveness of policy responses such as fuel tax reductions and direct compensation. The report highlights that low-to-middle income groups and residents of sparsely populated areas were most affected, and argues that short-term subsidies may conflict with Sweden's long-term climate goals of net-zero emissions by 2045.

This research paper examines securitization trends in Swedish climate adaptation policy between 2005 and 2022, analyzing whether the approach aligns with threatification, riskification, or normal politics through the lens of discourses, actor constellations, and tools.

This executive summary describes the States’ Electricity Transition (SET) Scoring system developed by Ember to evaluate the electricity transition across 16 Indian states, which represent 90% of India's annual power requirement. The analysis focuses on four dimensions: decarbonisation, power system performance, power ecosystem readiness, and policies and political commitments. While some states like Karnataka show strong performance across all metrics, others, particularly Bihar, Uttar Pradesh, and West Bengal, require significant improvements in decarbonisation and system performance to meet national targets.

This briefing by Ember and the Reform Institute analyzes the draft revisions to Poland's energy strategy to 2040 (PEP2040). It argues that the current draft is under-ambitious regarding renewable energy and over-reliant on gas, risking Poland's economic competitiveness and energy security by potentially making it the last major EU economy dependent on fossil fuels by 2030.
